NAME
ridsout -- convert IDSOUT format text file to IRAF images
.ih
USAGE
ridsout idsout_file iraf_file
.ih
PARAMETERS
.ls idsout_file
The text file or files containing the IDSOUT format data. This will most likely
be the redirected output from task \fBrcardimage\fR.
.le
.ls iraf_file
The IRAF file which will receive the data if the \fImake_image\fR parameter
is set. If multiple records are being converted, the output
filename is concatenated from this parameter and the IDS record number.
That is, images with these names would be created if \fIiraf_file\fR = "ids":
ids.1001, ids.1002, ids.1003, ..., ids.2001, ids.2002, ..., ids.3001 ....
.le
.ls record_numbers = "1001-9999"
A string listing the IDS records to be read.
.le
.ls make_image = yes
This switch determines whether the IDS records are converted to IRAF images.
When \fImake_image\fR = no, only a listing of the headers is produced,
no output image is written.
.le
.ls print_pixels = no
When this parameter is set to yes, the values of the ids pixels are printed.
.le
.ls long_header = yes
This parameter determines whether a long or short header is printed. When
\fIlong_header\fR = no, a short header is printed. The
short header contains only the record number and ID string; the long header
contains all information available
including the RA, Dec, HA, ST, UT, reduction flags, airmass, integration time,
starting wavelength and wavelength per channel information.
.le
.ls data_type = "r"
The data type of the output IRAF image. If an incorrect data_type or null
string is entered, the default data type \fIreal\fR is used.
.le
.ih
DESCRIPTION
IDSOUT format IDS records are read from a text file and optionally
converted to a sequence of one dimensional IRAF images. The text file will
most likely have been created by reading an IDSOUT tape with \fBrcardimage\fR.
The IDS records to be read from the file can be specified.
The IDS header information is printed in either a short or long
form. The pixels values can be listed as well.
.ih
EXAMPLES
[1] Convert all records in the IDSOUT file to IRAF images, with the root image
name being "aug83". The IDSOUT file is the first file on the tape, which is
mounted on mtb.
cl> rcardimage mtb[1] | ridsout aug83
[2] List the headers from the same IDSOUT file read in example 1, but don't make
output images. A \fBlong_header\fR will be listed; sample output is shown.
cl> rcardimage mtb[1] | ridsout make_image=no
.nf
RECORD = 2317, label = "CALLISTO 2297/2298 CLEAR/2.5ND",
oflag = OBJECT, beam_number = 0, alpha_ID = NEW, companion = 2318,
airmass = 1.524, W0 = 3430.735, WPC = 1.032, ITM = 960,
NP1 = 0, NP2 = 1024, UT = 3:36:20.0, ST = 15:36:43.0,
HA = 1:39:48.5, RA = 13:56:55.5, DEC = -10:42:37.1,
df = -1, sm = -1, qf = -1, dc = 0, qd = 0, ex = 0, bs = 1, ca = 0, co = -1
.fi
[3] Print the pixel values for records 5086 and 5087. No output image will
be written, and only the short header listed. Again, the IDSOUT file is the
first file on the tape, which is mounted on mtb.
.nf
cl> rcard mtb[1] | ridsout make- long- print+ rec = 5086,5087
.fi
.ih
BUGS
The current version of IRAF magtape I/O does not read beyond the first
volume of a multivolume tape.
.sp
Task \fBridsout\fR allows for converting more than one IDSOUT file per
execution. In cases where a given record number occurs in more than one
IDSOUT file being read and \fImake_image = yes\fR, this creates a problem, as
the images being written will have the same name for the duplicate record
numbers ("iraf_name.record_number"). The action taken in this situation depends
on the value of "noclobber"; the user should be aware of the potential
problem.
